DEVICE FOR SETTING rAsTENEa-s IN SHEET MATERIAL.

Application filed June 23, 1925. Serial No. 39,120.

This invention relates to a device for setting fasteners in sheetmaterial, and has for its object to provide a small portable handoperated device for setting a type of fastener known to the trade asChallenge eyelets in sheet material, as for example, through a pluralityof sheets of paper and thereby fastening said sheets together.

It is still further an object of the invention to provide a device inwhich the operations of punching the sheet material and setting afastener therein is accomplished with a single rocking movement of anoperating lever, the punching mechanism which includes the fastener tobe set, the

latter constituting a punch, being operated to perforate the sheetmaterial during the first part of the rocking movement of the operating.handle, a continued movement of said handle then operating a yieldingclamping mechanism and pushing the material downwardly upon saidfastener and against the flange at the bottom thereof with the bodyportion or barrel of said fastener projecting upwardly throughtheperforation. The fastener, with the material there on, is thenclamped'by said yielding clamping mechanism upon a rigid seat provided,

upon the base of the device, said. clamping mechanism compensating forthe various thicknesses of material that may be encoun tered, afterwhich the positioning pin upon which the fastener is mounted is allowedto drop by mechanism operated by the operating lever, thereby permittingthe latter to apply pressure to and collapse the upper portion of thebarrel of said fastener and compress the same against the sheet material.

The invention consists in a device for set ting fastenersin sheetmaterial as set forth.

in the following specification. and particularly as pointed out in theclaims thereof.

Like numerals refer to like parts througha out the severalviews of thedrawings.

In the drawings, 1 is a frame embodying therein a base 2 having a seatportion 3 formed thereon, said seat portion being raised a suitabledistance above the upper surface of said base. Projecting upwardly andforwardly from the rear of the base 2 is a neck 4 which terminates in ahead 5,

the upper portion of which is slotted at'6, thereby forming furcations 7between which an operating lever 8 is pivoted upon a'suitable pin 9. I p

Slidably mounted within the base 2 and projecting upwardly through theseat portion 3 of said base is a pin 10, the latter constituting asupport and positioning means for a fastener 11, the latter being of atype known to the trade as Challenge eyelets.

'The fasteners 11 areconstructe'd from a single piece of thin sheetmaterial, being formed with an approximately cylindrical shaped bodyportion closed at one end thereof and open at the other end thereof, andhaving a flange 12 extending outwardly therefrom at its open end, andsaid fastener has slits 13 which extend through the flange 12 and for agreater. portion of the length of the body as illustrated in Fig. 5.Thehead 5 of the frame 1 has a cylindri cal recess 14 formedthe'reinafnd located in longitudinal alignment with the positionsfastener, the material punched ing pin 10, and slidab'ly mounted withinsaid recess is a bottom member 15 of a clamp for sheet material A inwhich the fasteners 11 are to be inserted. The clamping member 15 isshouldered at 16, and a coil spring 17 surrounds said member, one end ofsaid spring engaging the bottom of the recess 14 and the other end ofsaid spring engaging the under surface of the shouldered portion 16 of:said clamping member. 1

Another member 18 is also slidably mounted within the recess 1 1 at theupper end thereof, said member also forming a portion of thehereinbeitore mentioned clamp, and said member 18 has a cylindricalrecess 19 extending downwardly from the upper end thereof, and acylindrical reee i 20 extending upwardly from the lower end thereof.Mounted within the member" and extending downwardly therefrom and intoand through the member 15 is a die 21, the latter having a head portion22 that is located within the recess 19 of the member 18. A coil spring23 surrounds the die 21, the lower end of said spring bearing againstthe shouldered portion 16 ot the clamping member 15, and the upper endof said sprin being located within the recess 20 of the clamping member18, and abutting against the upper end of said recess. The C011 The die21 has a hole extending upwardly therethrough, the diameter of said holebeing approximately the same size as the diameter ot' the positioningpin 10, and the lowr end of said hole co-operates with. the upperportion 01 a fastener 11 mounted upon the positioning pin 10 in forminga perforation in the sheet material A when the latter is forced by thedie 21 against said from the sheet material being forced upwardlythrough said hole 2 1 with each successive tion 22 oi the die 21. 'theoperating lever 8 adiace-ntjto and upon the outer side of each of thecam plates 25 are two other cam plates 26, each of which are adapted toengage the upper extremity of the clamp member 18. Located between thecam plates 25 is a cam plate 27, the purpose oi which will behereinafter mentioned. Each of the cam plates 25, 26 and 27 are securelyriveted together and to the operating lever 8, and in effect form a partof said lever, and when the latter is rocked, the various cam surfaceswill engage the die 21 and member 18 of the clamp and will actuate thesame in a manner hercinai' to be mentioned. I

Slidably mounted within the base portion 2 of the frame 1 and acting asa support to normally hold the positioning pin 10 in its uppermostposition as illustrated in Figs. and 3, is a member 28 having a f-shapednotch provided in its upper surface. member 28 is actuated at the propertime to *elease the positioning pin 10 and allow the latter to movedownwardly into the notched. portion 29 01" said member by a lever 30pivoted at 31 to the neck portion 7 ot the frame 1. 30 projects into anopening 32 provided in the member 28while the upper end of said leverthe cam plate 27 previously mentioned and as illustrated in Fig. 2, aspring 33 normally holding the various ter parts in the positionsillustrated. 'By releasing the positioning pin 10 as hereinbetorementioned, the fastener 10 18 pernntted to be colla sed by the die 21and the upper portion of said fastener is flattened V upon the sheetmaterial A and the various layers comprising saidsheet material aresecured together between the flattened portion oi? said fastener and theflange 12 there of as illustrated in Fl 7. A. pin 35% extending throughthe cam plate 27 limits the extent to which he lever 8 may be rockedtoward the left in Fig. 2. V 1

The general operation of the device her"- inbetore specificallydescribed is as follows :Assuming that the various parts are allpositioned as illustrated in Fig. 2, a fastener 11 is placed upon thepositioning pin 10 and a plurality of layers of sheet material which itis desired shall be fastened together are inserted between said fastenerand the lower end of the die 21. The operating lever 8 then rocked inthe direct on oi the arrow at, l and during'the ini a l portionoi thelUClxilIlg movement of said lever, the surfaces of the cams25 and 26engaging the upper extremities. of the. die 21 and clamping member 18respectively will ca said dieand clamping member to more downwardly inunison, the movement .tansmitted to the clampi member 18 'b beingtransmitted through the spring 23 to the lower clamping member 15,causing the latter to move downwardly in unisonwith t .ilc ntil t awr etr miti s'Qt said.-

The

. finally the die 21 and member 15 contact With the upper surface of thesheet material A.

The die 21 Will now cooperate with the fastener 11 to perforate thesheet material after which the downward movement of said die will ceasebecause of the contour of the earns 25. The cams 26, however, are soformed that the clamping members will continue to descend until thelower extremity of the clamping member 15 has forced the sheet materialA against the flange 12 of the fastener 11 as illustrated in Fig. 3.During this movement of the cams 26, the differences in the strength ofthe springs 17 and 23 will permit the clai-nping members to compensatefor different thicknesses of material that it may be desired to fastento get-her. As soon as the operating lever reaches a point in itsrocking movement Where the sheet material and fastener therein have beenclamped against the seat 3, the cam 27 ivill rock the lever 30 and movethe sliding member 28' from the position illustrated in Fig. 2 to thatillustrated in Fig. whereupon portions '25 of the earns 25 will engagethe upper portion of the head 22 of the die 21, and there being noresistance upon the positioning pin 10 onaccount of the fact that thenotch 29 is located directly therebeneath, the upper portion of thefastener 11 will collapse and be flattened against the upper surface ofthe sheet material A as illustrated in Figs. 4 and 7.

After a fastener has been inserted in the sheet material and flattenedthereag'ainst, the portions of said fastener that are located betweenthe slits 13 Will project radially from the body portion of saidfastener as illustrated in Fig. 6. v

In Fig". 8 I have illustrated a modified embodiment of my inve rtion inwhich a positioning pin 10 normally projects above the surface of theseat 3 a slightly greater distance than the height of the fastener 11with the result that when the die. 2] descends, the sheet material Awill first be perforated, after Whichthe closed upper end of thefastener will be punched therefrom. The clamp 15 Will then force thesheet material A downwardly upon the fastener and upper portion of saidfastener will be collapsed and flattened against the upper surface ofthe sheet material in exactly the same manner as previously mentioned.

The fastener When inserted in the sheet material and flattenedthereag'ainst Will appear as illustrated i'nFig. 9-, there being anopening extending entirely therethrough and the fastener will thereforeconstitute an eyelet. In all res ects, save the length of thepositioning pin 10, the mechanism and o eration thereof 7 is era-citythe previously set fdi'th connection With Figs. l to 7 inclusive.
